I love the game. Lot of fun. Biggest issue I have is the monster hit sounds. Some are really annoying but you can tell they are hit. While others feel like no feedback at all. Also had issues with the game sometimes making it seem like my bullets were just phasing through the enemy and no damage was taken. And at one stage transition, I got stuck on a box and thought I was going to have to close the game, but the box disappear and I was able to play more.
